Hi i currently have a custom build desktop (about a year old) with a HDD and SSD with the operating system(windows 7) on the SSD. Anyway when i boot up, the splash screen for the motherboard lags for a second and when i go into the bios and check the boot options the first option is set to windows boot manager but when i change it to the SSD and reboot i get the message about windows can't find bootable device so i have to use wbm (which is clearly slowing down my boot time). I have messed around and clean installed windows a few times, maybe the boot partition has messed up. Also when i look in disk management non of the partitions are marked as active which is pretty strange

I cant remember for sure, i got the ssd when i built the computer so the os has only ever been on the ssd but i cant be sure that everytime the hdd hasnt been plugged in. Do you think i will have to do a clean install again with just the ssd in. My motherboard is the gigabyte ga z77x up4th and in the bios menu its set to both efi and legacy mode i dont know if this has anything to do with it. Also my ssd is split into 2 partitions with a 100MB "system reserved" partition which is showing as "EFI system partition

Ok well I've had basically the same problem, easy fix here for you, basically if possible clean the ssd of all data (this can be done in the install) make sure you back it all up, then unplug the hdd, then clean install it come to the part where it asks you to choose the drive you want it to be installed on the only drive (YOU HAVE TO GO THROUGH THE ADVANCED OR CUSTOM SETUP) that should show up is the ssd, now you need to click the but that says partition or format or whatever it is, it'll prompt you saying this will result in a loss on all data press yes, now if alls well it'll complete that now click on it as your choice and install windows. You can now plug the hdd back in, remember to boot through bios and make sure the ssd is still listed as 1st boot priority. If so you should be right and it'll boot fine on the ssd from now on (make sure the ssd is plugged into the intel controllers and not Marvell)

It should say on your board (called sata 0) and Marvell is usually called M0, M1 so on, intel is the standard so it has automatic controllers, basically you bios standard settings will work it's just a matter of making sure you plug it into Sata 0

Some motherboard guides say some dont.

No it shouldn't

Ah ok thanks ill check it out later then :) yes i have already made sure it was on AHCI. I have also been adivsed that by having the ssd plugged into a non primary SATA connection this seems to work but i wasnt quite sure what they meant
